non-blocking read of serial port via BDOS?
Posted: Mon Nov 05, 2018 6:54 am
I seem to have a hazy recollection that any reads/writes through BDOS to the default serial port (RDR and the like) block until there is something to read. Is there any way around this? Am trying to find ways to support other systems for PLATOTerm without an explicit RS232 driver (such as the Tatung Einstein).
